In a power transmission line live-line crossing construction, by using the multi-bundle conductor pressing line pulley, the construction is not affected by geography, a pulling rope or conducting wire dropping groove phenomenon can be prevented from occurring effectively, and a pay-off construction of a special road section becomes relatively simple, easy, economic and safe.
Description
Technical field
The utility model relates to power transmission line wiring unit field, especially relates to a kind of line ball coaster.
Background technology
Continuous development along with the electric power rack; It is more and more that newly-built transmission line is crossed over situation such as power circuit, highway, railway, industrial crops forest belt, and tension stringing is crossed over construction difficulty, the particularly unwrapping wire in area, high mountain high hill day by day; The discrepancy in elevation is bigger between the iron tower; Very easily lead (leading) messenger, lead falls the groove phenomenon, becomes the principal element of restriction duration, influence safety gradually, has had a strong impact on safety, progress and the cost of power transmission sequence construction.Problems such as the line ball operating type that in the past often adopts was taked the line ball measure often temporarily, and the ubiquity facility are simple, poor reliability, unsafe factor are many.The present following problem of domestic and international existing line ball coaster ubiquity:
(1) common line ball coaster mainly carries out the architomy manual operation under artificial online; Apply downward strength; Make the unlikely groove that takes off of lead in the unwrapping wire process, but the manpower of ubiquity input too much, to personnel's technical ability have relatively high expectations, shortcoming such as affected factor is more.
(2) common line ball coaster does not take into full account the difference of bearing load, has certain potential safety hazard in the payingoff construction.
The utility model content
The purpose of the utility model prevents that lead breaks away from the line ball coaster of pulley block when being to provide a kind of unwrapping wire.
The technical scheme of the utility model is:
Multiple fission conductor line ball coaster; Comprise coaster framework and lead pulley, the lead pulley is horizontally installed on the coaster framework, and it also comprises the line ball boosting mechanism; Said line ball boosting mechanism comprises rotor plate, line ball pulley and side plate; Said line ball pulley be positioned at coaster framework one side and with the crimping tangentially of lead pulley, said side plate one end and line ball pulley spindle are rotationally connected, said coaster framework is provided with connecting axle; Said side plate and connecting axle are slidingly connected, and are connected with holddown spring between said line ball pulley spindle and the connecting axle; The race of said line ball pulley is corresponding with the race position of lead pulley.
Said side plate is provided with sliding tray, and said connecting axle and sliding tray are slidingly connected.
Between said side plate and the connecting axle for removably connecting.
Said coaster framework both sides are equipped with side plate and rotor plate.
The utility model is provided with a line ball pulley on the top of coaster framework; Through the line ball boosting mechanism; Line ball pulley and lead pulley are fit together, utilize the dynamic balance that raises up of downward elastic force of line ball boosting mechanism and lead during unwrapping wire, make lead unlikely groove that takes off in race.This device can be dismantled easily, and the exhibition of guiding rope is put convenient, flexible.
In power transmission sequence live across construction, adopt the utility model, can not receive the landform restriction, prevent to lead the generation that (leading) messenger, lead fall the groove phenomenon effectively, make the payingoff construction in special location become convenient relatively, easily, economy and safety.
The utlity model has application widely, adapt to the construction requirement in special unwrapping wire location, advantage is following;
1, the exhibition of guiding rope is put convenient, flexible;
2, the utility model has taken into full account the intensity of pulley block and line ball boosting mechanism, can satisfy the stress balance of lead in the unwrapping wire process, avoids occurring falling phenomenons such as groove, has reasonably distributed load, eliminates the potential safety hazard in the payingoff construction.
3, be connected the power appropriateness between line ball boosting mechanism and the lead coaster, both satisfied the line ball requirement, can also satisfy the condition that limp is passed through simultaneously.It is stressed even to guarantee in the unwrapping wire process that lead move in pulley, limits the swing of lead simultaneously, prevents groove, avoids lead impaired in the unwrapping wire process effectively.
Fall situations such as groove even 4 lead occurs, the side plate of line ball boosting mechanism can be opened, and is beneficial to the workman and falls the groove processing, improves efficiency of construction.
Use in the power line construction of the utility model under the power transmission sequence MODEL OVER COMPLEX TOPOGRAPHY, not only can guarantee the safety of payingoff construction, and remarkable in economical benefits.The construction of employing the utility model by traditional unwrapping wire mode, needs manning 2 people under every basic iron tower, each unwrapping wire section is calculated by 16 Ji Ta, reduces manual work and drops into about 11.6 ten thousand yuan.The benefit that minimizing brought of the raising of efficiency of construction and processing defective is remarkable equally.
This project can satisfy to produce to be badly in need of, and adapts to the development of electric utility again, has broad application prospects.
